VIP-Energy 5.0

VIP-Energy by StruSoft is a building energy modeling tool that helps architects, engineers, and energy consultants evaluate and optimize the energy performance and indoor climate of new and existing buildings. It supports annual energy balance calculations and time-step simulations to estimate energy use, heating and cooling demand, solar gains, ventilation and infiltration effects, and indoor temperature profiles. The software is designed for fast, reliable analysis during both early design and detailed engineering, enabling clear comparisons between design alternatives.

Key capabilities:

• Models the building envelope, glazing, shading, ventilation, and HVAC to provide a comprehensive energy picture
• Assesses thermal bridges and supports workflows that use StruSoft’s HEAT2/HEAT3 for detailed ψ-values
• Runs scenario and sensitivity studies to test design options and improve efficiency and comfort
• Uses climate data libraries and allows custom weather files for location-specific results
• Generates clear, audit-ready reports and visualizations for stakeholders and regulatory submissions

VIP-Energy streamlines energy analysis, helping project teams reduce operational energy, enhance occupant comfort, and demonstrate compliance with performance targets.
